DOI: 10.1016/j.dark.2018.100255

Abstract: Abstract We study the quantum avoidance of the big rip singularity in the Eddington-inspired-Born–Infeld (EiBI) phantom model. Instead of considering a simple phantom dark energy component, which is described by a perfect fluid, we consider… read more here.

DOI: 10.1038/s41586-025-09495-w

Abstract: Accretion disks in strong gravity ubiquitously produce winds, seen as blueshifted absorption lines in the X-ray band of both stellar mass X-ray binaries (black holes and neutron stars)1, 2, 3–4 and supermassive black holes5. Some… read more here.

DOI: 10.1093/mnras/staa991

Abstract: In 2019 November, MAXI detected an X-ray outburst from the known Be X-ray binary system RX J0209.6−7427 located in the outer wing of the Small Magellanic Cloud. We followed the outburst of the system with NICER,… read more here.

DOI: 10.1093/mnras/staf146

Abstract: We present results of cosmological zoom-in simulations of a massive protocluster down to redshift z ≈ 4 (when the halo mass is ≈1013 M⊙) using the SWIFT code and the EAGLE galaxy formation model, focusing… read more here.
